Plasma Display Panel and Drive Method Therefor

1. A plasma display panel including a pair of substrates which oppose to each other through a discharge space, a plurality of row electrode pairs which are disposed on one of the pair of substrates, a plurality of column electrodes which are disposed on the other substrate so as to extend in a direction intersecting the row electrode pairs and which form unit light emission regions in the discharge space at their respective parts intersecting the row electrode pairs, and fluorophor layers which are disposed at positions confronting the unit light emission regions between the column electrodes and the row electrode pairs, with a discharge gas enclosed in the discharge space, wherein: a secondary electron emission material is contained in said fluorophor layers; and said secondary electron emission material is magnesium oxide which contains magnesium oxide crystals that have a characteristic of presenting a cathode luminescence light emission having a peak within a wavelength region of 200-300 nm, when excited by an electron beam.

2. A plasma display panel as defined in claim 1 , wherein said secondary electron emission material is located at those parts in said fluorophor layers which confront the unit light emission regions.

3. A plasma display panel as defined in claim 1 , wherein said secondary electron emission material is mixed with fluorescent materials which constitute said fluorophor layers.

4. A plasma display panel as defined in claim 1 , wherein said secondary electron emission materials form layers, and they are stacked on layers formed of fluorescent materials constituting said fluorophor layers.

5. A plasma display panel as defined in claim 1 , wherein the magnesium oxide crystals have a characteristic of presenting the cathode luminescence light emission having a peak within 230 nm-250 nm.

6. A plasma display panel as defined in claim 1 , wherein the magnesium oxide crystals are magnesium oxide single crystals which are produced by vapor phase oxidation.
